Abstract
A voltage regulator circuit provides multiple control functions in respect to an automotive alternator including limiting of the field current to within a predetermined level. The regulator circuit includes a current control device for controlling the alternator field current, and a plurality of comparator networks to one of which is applied a field current reference signal and a sensing signal and to others of which are applied various alternator voltage reference signals and voltage sensing signals. The outputs of said comparator networks are employed in an OR fashion to control the field current control device.
